Abstract

The larvae of Black soldier fly (BSF), Hermetia illucens L., are reducing the environmental pollution through utilization of organic waste for their development on organic wastes and converting the organic waste into protein and fat rich biomass. Health promoting potentials of black soldier fly derived proteins as ingredient of diet appears to be crucial need of modern days. In present attempt, forty Norwegian Rats were utilized as experimental animals. The individuals of experimental animals were divided into four groups. Each group was consisted of ten individualsof the experimental animals. The groups of the experimental animals include: Untreated control group; DMBA treated group; Methanolic Extractives ofPrepupal Stages of Black Soldier Fly (MEPSBSF) Treated group and group treated with DMBA and Methanolic Extractives of Prepupal Stages of Black SoldierFly (BSF) (DMBA + MEPSBSF). Experimental animals sacrificed at the end of experiment. The enzyme superoxide-dismutase (serves to breakdown the oxygenmolecules of potentially harmful category); the enzyme glutathione-peroxidase (serving for reducing the hydrogen peroxide to water); the nitric oxide(compound responsible to cause widening of blood-vessels and stimulating hormones like insulin and growth hormone in human being); the enzyme myeloperoxidase(catalysing the process of formation of a number of reactive oxidant species); enzyme Asparate-aminotransferase and the enzyme Alanine-aminotransferase are theparameters considered for bioassay from the serum. Histopathological study on liver tissue was evaluated. The level of activity of enzyme Asparate-aminotransferase;the enzyme Alanine-aminotransferase; the level of nitric oxide; myloperoxide in serum and the level of nitric oxide; myloperoxide in the liver tissue appearto be significantly higher in carcinogen induced toxicity. The level of activity of enzyme Asparate-aminotransferase; the enzyme Alanine-aminotransferase;the level of nitric oxide; myloperoxide in serum in the group of experimental animals in the group: “MEPSBSF + DMBA” in comparison with the group ofexperimental animals in “untreated control”. The histological preparation of the liver tissue of the group of experimental animals in the group:“MEPSBSF + DMBA” reported less sinusoidal dilation; vacuolization in the cytoplasm of the liver cells (hepatocytes). There was inflammation aroundthe central vein and in portal region in the group of experimental animals in the group: “MEPSBSF + DMBA”. Methanolic extractives of prepupal stagesof black soldier fly (MEPSBSF) was reported to reduce the stress exerted through oxidation (oxidative stress). This may be through induction ofmechanism of antioxidation process of the contents of Methanolic extractives of prepupal stages of black soldier fly (MEPSBSF). The present attempton utilization of Methanolic Extractives of Prepupal Stages of Black Soldier (MEPSBSF) is reporting protective influence against the carcinogeniccompounds like DMBA.
